LUBRICATOR.

Application filed December 29, 1922. Serial No. 609,670.

To all whom it may concern Be it known that 1, JAMES J. I-lfENNEssY, a citizen of the United States residing at New York city, county of New York, and State of New York, have invented a certain new and useful Improvement in Lubricators, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this application.

My invention relates to railroad rolling stock and consists in a journal lubricator device adapted to be placed in the journal boxes of cars. l l I The present invention 1s a modificatlon and-an improvement upon the construction described and claimed, in o my copending Patent No. 1,444,461, and is illustrated in the accompanying drawings forming part of this application, in which- Figure 1 is a longitudinal section, through an axle box and journal equipped with my lubricator.

Figure 2 is a transverse section through the box showing the journal and lubricato in end elevation.

Figure 3 is a top view of the lubricator.

As those familiarwith the art are aware, there is a continual reciprocating movement of the car axle in the journal box and my lubricator is operated by this relative movement of the journal in the journal box. The lower portion of the journal box serves as a lubricant reservoir and my lubricator is inserted in the box beneath the journal and is maintained in central position by contact with the journal and the inner face of the bottom of the box and by a false bottom which surrounds the luhricator and contacts with the sides of the journal box.

The lubricator body, preferably cast integral, comprises a pump cylinder 1, a discharge passage 2, and an extended housing 3 the parts being so positioned relative to each other that when the lubricator is inserted in a journal box beneath a journal the discharge passage 2 will be somewhere near the longitudinal center of the journal and the housing 3 will extend outwardly therefrom to a point beyond the end of the journal.

A piston 4: is slidably mounted in cylinder 1 and is provided with a coil spring 5 which expands to thrust the piston to the left against the pressure of the vertical arm 6 of a bell crank pivoted at 7 on the hous ing and having its other arm 8 extending at an angle which adapts it to be engaged by the horizontal arm 9 of a second larger bell crank pivoted at 10 on the housing near the outer end of the latter. The other leg 11 of this large bell crank extends upwardly in front of the end of the journal 12 and has a yielding engagement therewith, similar to that shown in my above-mentioned application, including a springpressed conical button 18 engaging a corresponding recess 14& in the center of the end of the journal. A spring supported tube-15 is teleszopically mounted in discharge passage 2 and engages the lower face of journal 12. The tube spring 18 is light and is intended to keep the tube in contact with the journal and thus provides for any diiference in the heights of journal boxes or thicknesses of brasses and for the application and removal of a journal hearing or brass.

In operation, the back and forth shifting movement of the journal in the box will move the upper end of arm 11 of the large bell crank, thereby operating the small bell crank and piston 5 to thrust the latter to the right and. force any oil in cylinder 1 upwardly through passage 2 and tube 15. The ball check 16 will prevent any return of the discharged lubricant and when lever pressure upon the piston is relieved spring 5 will thrust the latter to the left which will cause lubricant to be drawn in through a flap valve 17 from the reservoir formed by the bottom of the journal box.

A false bottom 19 formed preferably of perforated sheet metal surrounds the lubricator and holds it against lateral movement in the box. This bottom serves as a support for waste which may be packed around the device and in contact with journal 12 in order to more thoroughly distribute the lubricant over the journal and to insure uniform supply of lubricant and continued lubrication in an emergency caused by the stopping of the pump.

The device is simple and economical to manufacture, occupies very little space and may be applied to and removed from a standard journal box without changing the construction thereof Various modifications in the details of my invention may be made without departing from the spirit thereof as expressed in the appended claims. r

I claim:

1. In a'railway journal lubricator, a body adapted to be positioned beneath a journal and forming a horizontal pump cylinder, a discharge passage and a housing extending outwardly from said cylinder and located above the axis of the latter, a piston in said cylinder, a bell crank pivoted to the undersur face of the top of said housing with a vertical leg engaging the outer end of said piston, a bell crank pivoted to the outer end of said housing with a horizontal leg extending inwardly of the housing and engaging the other leg of the first-mentioned bell crank,

' its vertical arm extending upwardly in front of the journ l and its horizontal arm extending rearwardly in said body toward said piston, a smaller bell crank pivoted in said body having its horizontal arm engaged by the horizontal arm of said large bell crank and having its vertical arm engaging said piston to operate the latter, and a discharge passage from said'cylinder to the journal.

3. In a railway journal lubnicator. a body forming a pump cylinder, a pump piston fit ted therein, a passage from said cylinder adapted to deliver to a journal under which the lubricator is mounted, a bell crank pivoted to said body and having one arm operably contacting with one end of said piston, an operating lever pivoted to said body having one arm operably engaging the other arm of said bell crank and having its other arm operably engaged by the end of said journal.

4. In a railway journal lubricator, a body forming a pump cylinder and a discharge passage therefrom, a piston in said cylinder, and a pair of intere ngaged bell cranks mounted on said body whereby m oven entof a journal, beneath which said lubricator is positioned, in a direction parallel to the ends of said piston and cylinder, may be utilized to operate said piston.

5. In a railway journal lubricator, abody forming a horizotnal pump cylinder and a vertical discharge passage therefrom, a piston in said cylinder and pair ofintere1 i-' eased b ll cranks mounte n sa body s that the end of a journal beneath which said lubricator is positioned may be engaged and horizontal movement of the journal maybe applied to said'piston in line with its axisf 6. In a railway journal lubricator, a reservoir housing adapted to be positioned in a journal box beneath a journal to be lubri- Gat a pump nde fo m d i i h r ing, a piston therein, compound lever operably engaging said piston and operably en; eas d by h e d f t e journ l where y movement of the journal will op erate said piston. v
